I was thinking....for those who have bought front brak upgrades, for instance Project Mu front 6 piston kit, what do you do with the otherwise well-above-standard front stock Brembos? Is there any way to fabricate a way to move the 12.9" rotors to the rear, and say use the 13.9 or whatever size it may be Gran Turismo's up front? SO you have 6 and 4 piston front and rear....just a though. Custom steel brackets couldn't be THAT hard to fab up...
